"First of all, he had a great attitude doing work on a Sunday of the Labor Day holiday. Then he performed the task of replacing a toilet and two new valve stems, in a really efficient and professional way. Just cannot say enough about his skill and friendliness, and would recommend him with my highest regards!"

"This guy is AWESOME. We got Jay in for a fairly simple plumbing job in the new bathroom, then we decided we wanted to get some new toilets, Jay said yes of course and it was done I also asked for new gas line no problem he said fixed. Then we asked him to fit three new vanities which she did efficiently and finally we asked the impossible about the new shower extending it out and he found a way. What can I say he did everything asked at a price that was very good he was an awful lot cheaper than the big boys because he doesn't have the overheads but I guarantee this guy gives you everything you ask for with a smile thank you Jay we will be using you again"

"I got a call from Kyle around 4:55 pm. He said he was able to come out around 7 pm, keep in mind, Hyper Flow closes at 5 pm. Kyle came out of his way after hours, ran a camera through my sewer line, snaked out the line, and then showed me on the camera the second time that the line was clearish. My main sewage line has been building up for a few years. Kyle gave me 3 different estimates for futures maintenance. I have already made an appointment for Kyle to come back out and do some more work. He is very up front, honest, and caring. He isn't just trying to get paid, Kyle is aware that life happens and works with customers to do what works best financially for the customer at the time of the job. I would recommend Kyle and Hyper Flow to anyone who is looking for a plumber with years of experience and has the best intrest for his customers."

"The toilets in one of our condominium rental units were backing up. We assumed that the line needed to be snaked. We calledAfford-A-Rooter and AJ came out to help us. After noting everything else was draining fine he realized it was the toilets themselves. Apparently, toilets build up a calcium deposit that can actually block flushing.. He told me what the problem was, and told me the best solution would be new toilets. It would have been as expensive to auger the crank toilets. He told me how much it would be if he were to do it, and, since I have replaced toilets in the past I told him I could do it myself. He agreed that would be the quickest and cheapest solution. He did not charge me anything for the service call. I appreciated his honesty and we will definitely use this company again."

Toilets FAQs, answered by experts

Usually it’s fine to leave a toilet clogged overnight, as long as it’s not close to overflowing. In some cases, the extra time may give the clog time to work itself out. For example, if it’s caused by an excess of toilet paper, letting it sit could result in the clog dissolving and you may be able to simply flush it away by the time you wake up. 

Only let it sit though if you have more than one toilet in the home.

No, you can’t convert a gravity-flush toilet to a pressure-assist toilet. Pressure-assist toilets include a tank-within-the-tank, and a standard gravity-flush toilet doesn’t have a capability to include the additional tank. If you want the benefits of a pressure-assist toilet, you’ll have to make the investment in a new one. 

The order of your bathroom renovation should prevent damage to the completed work. Start with demolition and removing the old fixtures. Then, address structural repairs or water damage, if needed. Next, tackle the rough-in phase for plumbing and electrical work, install waterproofing, and work on wall treatments like tile or paint. Install your shower or bathtub, toilet, vanity, and sink. Flooring goes in after major fixtures but before the toilet. Lastly, install new lighting fixtures, mirrors, and other finishing touches as desired.

Most toilets weigh between 50 and 100 pounds, depending on the material, size, and style. Some toilets can be disassembled into multiple pieces, which can make them easier to carry and dispose of. If you’re concerned that a toilet is too heavy to remove and lift on your own, enlist help or use a dolly to support the weight rather than carrying it yourself.

A wax ring can often last the entire lifespan of a toilet, which is typically 20 to 30 years. However, it may need to be replaced sooner if it becomes damaged. Signs that your wax ring needs replacement include bad odors or leaks coming from the base of the toilet. The wax can also dry out, flake, or crumble if the toilet was not secured correctly upon installation or has become loose over time. If you notice your toilet wobbles, it's a good indication that the wax ring may be compromised and should be inspected to prevent leaks.
